Power = (work done) / (time to do the work)
= (21,000 Joules) / (30 seconds)
= (21,000 / 30) joule/sec
= 700 watts
Answer:
Explanation:
k = Boltzmann constant =
r = Radius of gas molecule =
t = Temperature = 300 K
P = Pressure
Volume of gas per molecule is given by
From the ideal gas law we have
The pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior is
Answer:
17×10⁶ N
Explanation:
1 atm on Earth is 101325 Pa.
So on Venus, the atmospheric pressure is:
91 × 101325 Pa = 9220575 Pa
The force on an average human being would be:
F = PA
F = 9220575 Pa × 1.8 m²
F = 16597035 N
Rounded to two significant figures, the force would be 17×10⁶ N, or 17 MN.
